You can't know for sure what's going on without her telling you (and many therapists wouldn't). To me, she doesn't sound necessarily intimidated or inexperienced. Some clients like it when their therapist doesn't claim to be all-knowing, some actually feel more comfortable when the therapist admits s/he doesn't know this or that. That might be it.

You might like to let her know that you see her as intimidated and share this experience of others saying you are intimidating. This could lead to meaningful work for you.

I'm a bit more concerned that you feel like you've had a rupture after such a short time though.
